Re: [EnergyPlus_Support] WATER 2 AIR HP HTG MODE Round2
I agree, this sounds impossible. Ultimately, it must be expending some sort of
energy to take heat from the ground and move it to the building. Whatever it
is doing, from a modeling standpoint, it is simply a change in nominal heating
COP and part-load curves to match the manufacturer's heating performance data.
